This command is an example of conditional execution in a shell script.

The syntax is as follows:

if ${condition_command}; then starts the if statement where ${condition_command} represents the condition that is evaluated.
${echo "Condition is true"} is the command that will be executed if the condition evaluates to true. It will display "Condition is true".
else ${echo "Condition is false"} specifies the command that will be executed if the condition evaluates to false. It will display "Condition is false".
fi denotes the end of the if statement.

In summary, this command checks the value of ${condition_command}. If it evaluates to true, it executes the command echo "Condition is true". Otherwise, it executes the command echo "Condition is false".
